Erich Blume 483db74a3c Add SMART disk health monitoring and Ansible provisioning for sifaka NAS 
Adds smartctl_exporter alongside the existing node_exporter on sifaka,
routed through Caddy L4 TCP proxy at nas.ops.eblu.me, with a Grafana
dashboard for disk health visibility. Introduces the first Ansible
playbook for sifaka (mise run provision-sifaka) and shared exporter
port variables in group_vars/all.yml.

Backup

Sifaka is the target for backup, not a backup source. borgmatic sends backups TO sifaka, not OF sifaka.

Data protection for sifaka itself currently relies on the Synology RAID 5 configuration, which provides single-disk fault tolerance. Future plans include offsite duplication for additional resiliency.
